CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 399,532, dated March12, 1889.

Application filed April 14:, 1887.

1 0 (oi/Z whom, it may concern:

lie it known that I, ALEXANDER HERON, a subject of the Queen of (SilentBritain, and a resident of Delaware township, in the Province ofOntario, Canada, have invented certain new and useful Improvements onCar- (louplers, of which the following is a specification.

This invention relates to a device for coupling cars together in atrain, and one which is simple in omistruetion and reliable and durablein operation, and one which can be adjusted and set instantly in such amanner that the cars may be coupled when they come together, or cometogether and part again without coupling, as required, and the operationof adj usting and setting the coupler to couple the cars is performed atthe side out from between the cars, so that the operator will not beexposed to any danger from accident of any kind when. adjusting andsetting my llllPlOYtKl coupler; and this invention consists ot theimproved construction and combi'natioi'i olj' parts of the same, as willbe hereii'iat'ter more fully described and claimed, reference being hadto the accompanying drawings, wherein- Figure 1 is a side elevation oftwo drawbars, partly in section, attached to two adjacent cars, andshowing their position when coupled together. Fig. 2 is an enlargeddetail perspective view oi the coupling pin or link. Fig. 3 is a detailperspective view of a modification oi Fig. Fig. l is an end elevation ofa car and draw-bar, showing the devices which revolve the d raw-bar andthe draw-bar in the position both draw-bars and links are when coupledtogether. Fig. 5 shows one of the draw-bars in position to uncouple orto receive the coupling pin or link when coupling. Fig. U is a planview, partly in section, slnnving the flanges on the entering end of onecoupling link or pin engaging with the shoulders of the adjacent cou'ilingli nk or pin.

A designates the platform, and l3 13 the floor-beams, ot' the ear, inwhich. the drawbar (l is held in place, and this draw-bar C may be openor closed on the top, as required. Part of the draw-bar is formed roundin moss-section, as shown at G, where it is sup- Serial No. 234,887! (Nomodel.)

ported in the floor-beam l), to permit said (ll'tLW-bfti and couplinglink or pin F held therein to be revolved laterally to couple with. oruncouple from the draw-bar of the adjacent car.

l) is a rod secured to the draw-bar t. This rod D extends through thefloor-beam 1;, and on each side of this l'loor-beam l3 springs E E areheld in place on this red D the spring E to ease the jar when thedraw-bars strike together when shunting or coupling, and the spring E toease the strain oi? the cars on the draw-bars when starting the train.

1: designates a link or pin pivoted on the pivot-bolt G, the latterbeing secured in the draw-bar t, and this link or pin 1" is formed withan aperture, l through which the pivotbolt G passes. This aperture F ispreferably formed larger in cross-section than the pivotbolt G, topermit the'coupling link or pin 11 to work perfectly free, and to permitthe end F of one of the links to be placed on the ledge (1' ol' the draw-bar, if required, when adjusting the drawbars and links, so that thecars will couple when they come together. The entering end if of thelink or pin F may be formed. integral with the main part F, as shown indraw-bar Fig. l, or it may be secured thereto by a nut, n, screwed 011ascrewthread formed on. the end F in the slot F, as shown in the adjacentdraw-bar C in Fig. 1, so that it' this end F should become accidentallydamaged the latter construction presents an easy, simple, and cheapmethod of renewing said end W.

l? is a slot extending vertically through the center of the couplinglink or pin l5, and F is a longitudinal slot through the center of thecoupling link. or pin L, which terminates in the vertical slot F". Thisslot 1? is square in cross-section, and the slot F" is larger in onecross-section than the cross-section at right angles thereto, and thesquare slot F is as large in cross-section as the larger crosssection ofthe slot 1:". This forms shoulders 11, and behind the portion whichnarrowest in cross-section, immediately at the inner end ol the slot 1:;and the entering end F of the einipling link or pin 1? in onecross-section is fitted to enter the narrow cross -seciion of the slot Fperfectly free, and the flanges a,

formed integral with the entering end F will not pass through the narrowcross-section of the slot F, but will freely pass through 5 the largercross-section of the slot- F, and these flanges 71 will turn perfectlyfree in the slot F, so that when one draw-bar, O, and coupling link orpin F, secured therein, is revolved laterally in its bearings in thefloor-beams B until the slot F in the coupling link or pin F is in theposition shown in Fig. 5, the entering end F of the link or pin F of theopposite draw-bar will freely enter and pass through the slot F into theslot Fibecause the flanges n will be opposite the longer cross-sectionof the slot F Then by revolving this draw-bar C and coupling link or pinF secured therein to the position shown in Fig. 4 these flanges 91/ comeopposite the narrow part of the slot F in the slot F and engage with theshoulders F to completely couple and lock the draw-bars together. Thenby revolving this draw-bar to the position shown in Fig. 5 again thecars are uncoupled and may freely sepa- 2 5 rate, because the flanges ncome opposite the longer cross-section of the slot F Thus the cars maybe coupled or uncoupled, and when the coupling link or pin F of onedraw-bar is in the position shown by dotted linecc in Fig.

0 1 the ears may come together and part again without coupling.

In Fig. 3 is shown a modification of this link or pin F, which ispreferably used when coupling a draw-bar formed with my improvement.

3 5 To one having the common ordinary link and pin the flanges n on theend F engage with my draw-bar, as hereinbefore described, and the linkis removed from the common drawbar, and the pin of the common draw-baris passed through the latter as well through the aperture 0, formed insaid modification shown in Fig.

H is a lever pivoted on the end of the car, and I I are rods com'iectingthe lower end of lever H with the draw-bar and one ormore of these rodsI may be used as required for the purpose of revolving the draw-bar whencoupling or uncoupling; and J is a cog-segment, K a dog, and L a spring,&c., for holding the lever in any required position to Which it may beadjusted, as well as the draw-bar in connection therewith, to hold thecars together when coupled, or to permit the cars to be coupled oruncoupled, as required.

Each end of each car is intended to be provided with a lever, H,'orother suitable operating device and attachments, but at the alternateside on each car, or on the alternate side at each end of the same car,so that the cars may be readily and easily uncoupled or coupled fromeither side on which the operator may be at that time.

Having thus described my invention, I claim 1. In a car-coupling, thedraw-bars 0, formed round in cross-section at C and revolvinglaterallyin their bearings, in combination with reversible coupling links or pinsF, which are secured in and revolve laterally with the drawbars, andformed with longitudinal oblong slots F vertical slots F shoulders F andentering end F formed with flanges n, as and for the purpose set forth.

2. In a car-couplin g, the draw-bars (7, formed round in cross-sectionat C and revolving laterally in their bearings, and reversible couplinglinks or pins F, which are secured in and revolve laterally with thedraw bars, and formed with longitudinal oblong slots F, vertical slotsF", shoulders F and entering end F formed with flanges n, in combinationwith the lever ll, cog-segment J, dog K, spring L, and connectin -rods II, as and for the purpose set forth.

In testimony whereof I ai'iix my signature in the presence of the twoundersigned witnesses.
